38          ## What?
39
40          Updates `flake.lock` to the latest revisions of all flake inputs (`nixpkgs`, `flake-utils`, etc.).
41
42          ## Why?
43
44          Keeps Nix inputs current so contributors and CI build against fresh `nixpkgs`. Picks up upstream security and toolchain fixes. Generated automatically by the flake-lock update workflow on changes to `go.sum`.
